Subject: [PATCH v3 0/5] scsi: ufs: support LU Dedicated buffer type for WriteBooster

Hi,

This patchset adds LU dedicated buffer mode support for WriteBooster.

In the meanwhile, enable WriteBooster capability on MediaTek UFS platforms.

v2 -> v3:
  - Introduce a device quirk to support WriteBooster in pre-3.1 UFS devices (Avri Altman)
  - Fix WriteBooster related sysfs nodes. Now all WriteBooster related sysfs nodes are specifically mapped to the LUN with WriteBooster enabled in LU Dedicated buffer mode (Avri Altman)

v1 -> v2:
  - Change the definition name of WriteBooster buffer mode to correspond to specification (Bean Huo)
  - Add patch #5: "scsi: ufs: cleanup WriteBooster feature"

Stanley Chu (5):
  scsi: ufs: enable WriteBooster on some pre-3.1 UFS devices
  scsi: ufs: add "index" in parameter list of ufshcd_query_flag()
  scsi: ufs: add LU Dedicated buffer mode support for WriteBooster
  scsi: ufs-mediatek: enable WriteBooster capability
  scsi: ufs: cleanup WriteBooster feature
